ROTARY WRAPPlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 541,141, dated J' une 18, 1895.

Application iiled October 2, 1893. Serial No. 486,963. (No model.)

To all whom it may concern:

Be it known that I, DANIEL WRIGLEY, a.

subject of the Queen of Great Britain, and a resident of New York, in the county of New York and State of New York, have inventedy a certain new and useful Rotary Vrapping- Machine, of which the following is a specification.

My invention relates to machines for wrapping newspapers, pamphlets and the like and includes simply the mechanism for Wrapping and discharging the thing wrapped.

The machine is designed to be attached to any folder whether said folder is or is not directly connected to a printing press. Its purpose is to receive the thing to be wrapped in the form ready for rolling and Wrapping and along with it the pasted wrapper, to wrap the one within the other and in the act of discharging them from the machine to press the two down iiat in a manner to insure the close adherence of the pasted edge.

My machine is best adapted for attachment to those printing presses with which folding and pasting attachments are already combined.

My invention does not extend to the folder nor to the pastor but simply deals with the folded paper as it is lusually delivered from a modern press and with the pasted wrapper both of which are fed together directly into my machine by hand or otherwise.

My invention consists in the combination and arrangement of parts as hereinafter described and pointed out in the claims.

In describing the invention reference is made to the accompanying drawings which form a part of this specification, and in which- Figure l represents a plan View of my rotary wrapping-machine. Fig. 2 represents an end View looking at the delivery end. Fig. 3 represents a View of the opposite end, and Fig. 4 is avertical section taken in the plane represented by the line et 4 in Fig. 2.

The supports for some of the parts are not shown, it being understood that in adapting the machine to different presses the framework thereof will furnish supports for the said parts and the usual mechanical expedients will be resorted to in making such adaptation.

The parts directly involvel in the wrapping operation are supported upon or in close proximity to the end brackets 5, which are provided with suitable foot pieces for attaching '9. These bearings are spring seated in the rims of the brackets 5. Each bearing is pro 65 vided with a shank l0, seated in a socket in the rim of bracket 5. A portion of said shank is reduced and screw-threaded and extends through a reduced portionof the socket out beyond the periphery of said rim. Upon the 7o protruding ends are placed jam-nuts 11 for regulating the distance of the nipping roller from the wrapping cylinder and for securing to said shank the abutment 12.

Each abutment has at its ends perforations through which pass the steady pins 13. Said pins are secured in the rim of bracket 5. The function of the abutment will be disclosed farther on.

About each shank 10, within its socket is a 8o spring which serves to cushion the pressure of the nipping roller and to return the same to place after the ejectment of each wrapped paper. Instead of the spiral springs thus used, I may employ other sorts of springs. For instance, plate springs may be attached to the inner surface of the rim of bracket 5, and press upon the bearings 7.

The wrapping cylinder is supported at one end only and there by a broad bearing as in- 9o dicated at 14.

At 15, is represented one of the feeding rollers, around which and the first nipping roller.

8, passes a feeding web 16. Above roller 15,

and geared thereto is roller 17, which is geared 9 5 to the cam operating gear 18. With the gear 18, also meshes the upper cam operating gear i 19, and with this gear meshes an idle gear 20, which transmits motion to the pinion 21, on

the wrapping cylinder. With this pinion 21, roc.

Y chine.

mesh the pinions 22, which-are mounted on the ends of the nipping rollers.

The construction for the ejection of the wrapped papers is as follows: Upon each bracket 5, near each nipping roller is located a lifting lever 23. Rods 24, pass through bearings in both brackets and on their ends are keyed these lifting levers. The outer ends of said lifting levers are bent at an angle to the main portion of the levers and bear against anti-friction rollers 25, mounted upon the abutments 12. The tive levers 23, at each end of the machine are coupled together by a circular rod 26, to which they are pivoted. This provides for the simultaneous action of alltheliftinglevers. Thepivotjoiningoneof these levers to the rod 26, is extended through said rod and provided with an anti-friction roller 27, in the path of the projection on the cam wheel 28, which is attached to gear 18. As this projection strikes said roller, the lifting levers are all forced over and their bent ends pressing against the abutments 12, cause all the nipping rollers to move outward from the wrapping cylinder. ThisV leaves the wrapped paper free to be forced off the end of the cylinder 6,.by the action of the ejector.

The ejector is axially disposed with respect to the wrapping cylinder and is constructed and operated as follows: The wrapping cylinder is bored from the journaled end and in said bore is seated a push rod 29, against a spring v30. Through the inner end of the push rod is passed a pin whichprojects through slots 3l, in the cylinder 6. The ends of this pin pass also through the ejector ring'32, which encircles the cylinder 6, at the gear end. From this it will/be seen that the main parts constituting the ejector, namely, the push-rod and ring, are, with .respect to cylinder 6, concentrically orcoaXially arranged to have their axes in common, constituting, as expressed above, an axial disposition of the ejector with respect to said cylinder.v The push rod 29, projects beyond the wrapping cylinder and has a bearing for the projecting end in a block 33, which is retained in place by two pins secured therein and seated to slide in ways formed in the bearing 14, of the wrapping cylinder. Against this block 33, rests an anti-friction roller in the forked end ofthe ejecting lever 34. This lever is pivoted at 35, to any convenientsupporting means upon the press or upon thev end'bracket 5, but preferably to the press. Upon the upper end of the ejection lever is mounted a roller 36, in the path of the projection upon the cam wheel 37 which is operated by the gear 19.

The delivery rollers which receive the wrapped paper as it is ejected from'the cylinder 6, are mounted at the end of the ma- 'lhe two inner ones 38, are arranged as close to the wrapping machine'as possible so as to receive the wrapped paper immediately upon its leaving the wrapping cylinder. The outer roll-ers 39, are placed close to the inner ones and are spaced apart the required distance to completely flatten the paper as it passes between them. 1

The operation of the machine is as follows:

VThe paper andthe pasted wrapper are received between the receiving rollers l5 and 17, the wrapper lying under the paper, and by the web 16, they are carried forward to the wrapping cylinder, and are set at a distance apart but little less than the diameter of the wrapper paper, so as to receive the paper readily from the wrapping cylinder between which and the nipping roller 8, they are caught and carried around the cylinder being held there againstby the succeeding' nipping rollers v9. The wrapping cylinder is calculated to make about two and one half turns for each paper which is sufficient to wrap any paper now printed. As it completes this number of turns the pasted edge of the Wrapper reaches the 'nipping roller 8, or the one diametrically opposite to it according to the size of paper to be wrapped and consequently the length .of the wrapper. As said cylinder completes each two and one half turns the projection on cam wheel 28, strikes the roller 27, and forces the circular rod 26, to the right, as seen in Fig. 1, which carries all the lifting levers 23, with it and they in turn by bearing against the rollers 25, on the abutments 12, retract the nipping rollers. This leaves the wrapped paper resting freely around the cylinder 6. The gearing is so proportioned and timed that as soon as the nipping rollers have been retracted the projection upon the cam wheel 37, will strike the roller 36, on lever 34, and force the friction roller in the lower end of said lever against flattened faces of the wrapped paper as saidl paper passes between the delivery rollers and the adherence thereof will be positively insured. The wrapping cylinder is in continuous rotation and the instant one wrapped paper is ejected from it another begins to wrap about it, the nipping rollers having been returned to place by the springs about the Shanks of their bearings. The distance of said rollers from the wrapping cylinder being regulable by means of the nuts'll, the machine is adapted to Wrap papers and paniphlets of various thicknesses.

Motion may be transmitted to the wrapping mechanism and also to the delivery rollers from any suitable or convenient part of the press. The delivery rollers may also be made Various changes may be made in the details of construction and in the arrangement of parts Without departing from the spirit of my invention.
